Technical field
The present invention relates to technical field of coatings, more particularly to a kind of heat-reflecting heat-insulating diatom ooze.
Background technology
Current building energy consumption accounts for the 30% of whole society's energy consumption, wherein main is due to the use of air-conditioning.Hot summer,
Sunlight is absorbed by roofing and is transferred within doors, indoor temperature is lifted, according to statistics, when roofing receives sunshine by direct projection to roofing
Between it is most long, and the heat that roofing absorbs accounts for house always absorbs heat 46%, therefore researches and develops insulating mold coating for construction tool
There are great economic benefit, environmental benefit and social benefit.
By reflective insulation coating brush on building surface, it becomes possible to reduce that building Xia Redong is cold and hot summer and warm winter region,
Low emissivity heat transfer structure is formed, improves building structure heat insulation, so as to reach the mesh for reducing air conditioner refrigerating energy consumption, saving the energy
's.Its mechanism of heat insulation is high mainly due to heat reflectivity, effectively reduces radiant heat transfer and convection current heat transfer.But use at present every
Hot coating is such as easy to aging over time and easy to wear by solar radiation also there are many shortcomings, can thus to apply
Expect that heat insulation variation, the service life of film shorten.
The present invention provides a kind of heat-reflecting heat-insulating diatom ooze, has excellent heat reflection cooling-down effect.
